To all whom t may concern:

Be it known that l, HARRY l-ll. ADAMS, a. citizen of the United States, residing at Chicago, in the county of Cook 'and Stato of illinois, have invented a new and useiul Improvement in Vehicles, of which the following is afspecilication.

My invention relates more particularlyto passenger-carrying vehicles such, for example, as'l street cars,.busses, and the like,

and more especially to vehicles of the character stated employing one person only in their opera-tion, such kind of vehicles being commonly known as one man control vehicles. f c

My object, generally stated, is to provide a vehicle of the character stated which may be controlled by one operator and which shall present means presenting a barrier to the boarding of the car by passengers through the exit passageway on the platform, but which will not present obstruction to the alighting from the car of passengers from the exit-way, these means being preferably controlled automatically by the movement ot' the passenger through the exit-way in alighting from the car, the purposebeing to renderunneoessary any at tention, on the part of the operator, to the attempts of persons to board the car through the exit passageway, and prevent# ing the boarding of the car by persons through the passageway without requiringl anyattention on the part of the operator for preventing such unauthorized boarding of the car. l

ln cars of this character, the fares are collected, usually, at a point adjacent the location of the operator who is positioned at .the motor-controller, and it is his duty to see thatftares are collected from the. passengers boarding the.v canv through the en trance-Way on the platform, and it is one of my objects to permit the operator to center his attentionl on the collectionof the fares without requiring himto give any attention to theattempts of persons to gain unauthorized access to the car by boarding it through the exitway,esp.ecially while hewis engaged in-collecting fares. e *f` Referring to the accompanying drawings;

. Referring to the construction shown in Figs. 1 to 7 inclusive, the front platform of the car is represented at 20, it being shown as a continuation of, and on the same level with, the floor 21 of the body portion of the car, the front cross seats of which are represented at 22 affording the aisle 23 therebevided with 'from and preferabl A as are ,commonly tween. The. car is shown as provided with a ,lengthwise-extending' seat 24 at thev closed side of the platform but shorter, seat 25 at the other side of the platform. The various stanchions at this end V-ofthe car, for supporting the vadjacent side walls and roof, 27 and 428, the stanchion 27 extending in front of the seat 25, the side of vthe car be-` tween the stanchions 27 and 28 resenting an opening which may be, andas s' own is, profolding doors hereinafter referred to; The operators seat is represented rat29 and is so locatedV as to renderl readily -operable the motor-'controlling mechanismv represented at 30 and mechanism represented at 31 for controlling the platform cors just a rail 32frising thereof thegeneral curved form shown, this rail terminating at itside- 20 is provided wit pending end portion 33 preferably at a point"A 4on the plat-form` substantially midway between the sidesof the latter andi in advance of thefcross seats 22, the rail thence extendlng curving Y tween thestanchions 27 and 28 adjacent to which its outer extremity -34 extends sub- Y stantially midwayjetween these stanchio ns,'`

trance-way represented at 35 which extends adjacent the position of the operator at 2.9, and an exit-way represented at 36, both of these ways opening at one end into the interior of the car and at their other ends through the space between the stanchions 27 and 28, there being preferably provided to extendpart way in the exit-way 36, a rail 37 secured atone end to thel stanchion 27 at a point above the fioor and at. its opposite, inner, depending. end to the platform.

The 'opening between lthe stanchions l27 and 28 is shown as provided with folding doors hereinbefore referred to and represented at 38 and 39, these doors meeting adjacent the post 32 and each being preferably formed of sections hinged together as shown, these doors being hingedly connected at 40 and 41 to the stanchions 28 and 27 respectively, and guided at their outer sections as by guides at the top of the said open- V ing, all in accordance with common practice,

the platform 2O alsol being provided with steps 42 hngedly connected therewith as is usual in street car structures. The doors 38 and '39 are shown as controlled by the op erator located at the seat 29, by manipulation of the controller device 31 which, in a manner not shown but which in common practice, serves to control the operation of a door-operating motor represented at 43 Vand located above the doors, this motor operating a crank portion 44 which in operating reciprocates a slide-member 45 having link connection 46 with the door 38 and operative connection with the other door 39, for simultaneousl operating it, through the medium cfa lin 47 pivoted to one end of a rock lever 48 fulcrumed at 49 to the platform and connected at its opposite end with a link 50 pivoted to the door 39. `Connections also may be provided between the o l erating mechanism stated and the movab e step 42 for causing the step to be swung to horizontal 'posltion upon the openihg of the -doors and. swung to vertical position upon the closing of thedoors. The mechanism for j 'The exit-way 36, in the construction shown, is provided with barrier means hereinbefore referred to, located at the inside of the door 39 and shown as formed of two c- -tions 51 and 52 in the form of leaves which nnected at their edges with upwardly-extending rotatable shafts 53 and 54 jurnaled, at .their `upper ends in 55 and 5.6 extending, respectively, from t e rail 32 and the stanchion 27, their lower ends bein journaled inbra'ckets 57 and 58 connecte with the frame of the car, The shafts 5 3 and 54 are connected together" for simultaneous movement in opposite di- I rections, namely,

' .connected at -71 with a crank The gate ysections 51 and 52 means'which operate to swing the` gate sec `thearm 81 of this lever raasraoo to swing the gate section 51- on its ivot 53 in counter-clockwise direction in ig. 1 and the gate section 52 in clockwise direction in thisy figure, through the medium of crank arms 59 and 60 secured to the shafts 53 and 54 and connected together by a link 61 pivoted thereto at its ends.

cooperate with tions to closed, obstructingposition shown in JFigs. 1 and 3, this-mechanism comprising alever 62 fulcrumed between its ends at 63 on a bracket 64 depending from the under-frame of the carand havingits longer, lower, end weighted las indicated at 65, the opposite end'66 of this leverwhich is shown 'as of bell-crank form, being pivotally con# nected, as indicated at 67, with a link 68 which in turn is pivotallyl connected at 69 with a link 70, the latter being pivotally arm 72 secured to the shaft 54, the arrangement of the parts described being such that when the gate sections 51 and52 are swung outwardly, by a passenger, in leaving the car, pushing against the gate, the gate sections will be automatically returned to closed, obstructing, position across the exit-way 36.

The gate mechanism referred to also cooperates with mechanism operating to releasably lock the gate sections against movement, these means, in the particular embodiment of my invention, which is now being described, comprisingan arm 73 rigidly secured to, and extending laterally from, the shaftI 54 pending from the car platform, the other `end of this lever extending `beneath the end vportion 78 of an angle-shaped lever 79 the arms of which are represented at 8() and'81,

this'lever being connected at the upper endof its arm'80 with a shaft its ends` in brackets 83 secured to the under side of the platform,

4 being Tweighted as indicated at 84, and the tendency of this weight being to rock the shaft 82 in clockwise direction in Fig. 5. equipped at its vopposite ends with arms 85 which extend into the 4same portions 80 of the lever 79. Pivotally connected with the arm 80 at the-left hand side of its pivot 82 in Fig. 5,` and with eX- tremities ,of the arms 85, as indicated at.

86 and 87, are yokeashaped clips 88 provided leo with upwardly-extending stem ortions'89 which extend into downwar lys-opening ,sockets 90 provided on the underside of a plate-liketreadle 91, intermediate' the ends of the. latter, this treadle being located withatform 20 and p for cooperation with the notched portion 74 of a lever`75 fulcrumed between its ends, at 76, on a bracket 77 de-4 82 journaled at the extremity of The shaft 82 isv position as the a passenger walks throughthe eXit-wayf' toward its outer end, this treadle belng shown as hinged at t-he ,edgethereof 'adjacent the openl side of theV platform, as represented, at' 93. The treadle 91 is prevented from rising to ,a position in which 1t extends above the level of the platform 20 by the provision of a stop lug 94 depending from the under side thereof and extending into overlapping relation relative to a port-ion 95 of the car platform, the parts, as shown, being so proportioned and arranged. that the treadle l91 may have a limited 'swinging movement in bothy directions sufficient .to actuate the mechanism controlled thereby as hereinafter described.. rllhe provision of the several push rods 87 at the ends and toward the center of the treadle serves to insure the proper operation of the shaft 82 whether the passenger stepsupon the treadle at either edge thereof or same direction and causing the portion. 78

thereof to bear down on the adjacent end of the lever 75. This results in rocking the .lever 75 to a position in which its opposite end disengages, at its notch 74 from the arm .73, thereby causin@ the sections of the gate to become unlocked and permitting the passenger, by pushing against the gates, to

continue through the gate-way and alight from the car (the operator of the car hav' ving opened the doors 38 and 39), the gate swinging outwardly against the resistance .of the weighted lever 62. `When the passenger has passed beyond the gate, or' the last passenger of a number thereof leaving the car, where the passengers follow closely after each other,vhas passed the gate, the gate sections automatically return to the obstructing position shown in l11 ig. l, under the action of the weighted lever 62 which swings downwardly to normal position, the" armv 7 23 in this movement swinging into interlocked engagement with Mthe notchedI portion 74 of i the lever 75 to releasably lock the gate against actuation until again released by a passenger stepping `upon .the treadle 91."

rlhe cam surface 96 is provided to insure r against the jamming of the end surface of the arm .73 4against the side of the lever 75 in'the'return movement referred to, the

l enoa ement of thel arm 73 with the cam surface 96 servinnr to liftthe lever 7 jand permit the arm 73 to ride against'the under side of the lever 75 into interlocked relation Y with the notch 74. Referring to the construct-ion shown in Figs. 8 to 13 inclusive," the barrier means for 'the exit-way 36 and controlled by the passenger, comprise the door 39 formed ot sections and supported, as hereinbefore described, a'nd the operator of the ear controls the opening and closing of the door 38 only, this being effected ythrough the motor 43 from a controlling device such as that referred to by the numeral 31 in Fig. 1. In this particular arrangement the door 39 is automatically Vopened by the passenger walking across the floor of the exit-way 36,

yand'automatically returns to closed condij indicated at 99. The sides of the recessed portion 97 are so formed as to presentledges 100 and 101 serving as stops for'limiting the dow-nward'movement of the treadle 98. Located below the platform 20 is a switch device shown-as formed of a pair of vContact members 102 `and 103 supported in a block 104 of insfulatingmaterial secured to the interior of a casing 105 fastened to the under side oyf the platform, and housing switch contacts 102 and 103, these contacts being normally spaced apartl as shown. A plunger 106 of insulating material is reciprocable'vertieally in an opening 107 in the top of the'fcasing1057and Serves' as a means'by which, when theg-treadle 98 is swung downwardly by a passenger stepping upon it, the contacts 102 and 4103 are forced into engagement with each. other. The door 39 in this construction is operated by a gateopening-and-closing .motor 108,- separate from the motor 43 and preferably located near the roof of the car, this motor, which is of the-same internal construction as thoseher`einbefore referred to, comprising acasing 109 containing pistons 110 and 111 operating in cylindrical portions 112^and 113of lthe casing, these. pistons being`A connected by a rod 114 presenting gear-teeth 115 yalong' its upper edge with which'` mesh the-teeth of a segmental rackv '116 secured to a sha-ft 117 providedwith a crank arm 118 through the medium of which the door 39 is operated to open and. close it bythe engagement of thecrank 118 with thewallsof ar slot 119 rising ifrbm a bar 120 supported to be lengthwise rec'iprocable and pivotally connected at one endwit'hQdoor-operating levei` mechanism formedr of the levers 122, 123 and 124 pivotally connected with the door 39 and a bracket 125cm a stationary part of the car, this lever. mechanism operating to move the sectional door 39 into open )ositioii upon moving the bar 120 in one direction and into closed position upon operating this bar in the opposite direction, the lever mechanism just referred to being of such construction and arrangement, and operating, as in the case of mechanisms conimonly provided for operating street car doors.

The motor 108 also comprises, in accordance with common practice, the heads 126 and 127 closing the ends of the cylindrical port-ions 112 and 113, respectively, each of these heads being provided with a passage 128 continued into the wall of the adjacent cylindrical portion of the casing, and opening into the interior of the cylinders at 129, thesef passageways having seats 130 controlled by ball-checks 131 which close toward the cylinders with which they, iespectively, cooperate. The passages 128 also contain seats 132 controlled by ball-checks 133 which close iii the same direction as the ball-checks 131. Passages 134 in the heads open into the cylindrical portions 112 and 113 and into the adjacent passages 128, between the ball checks 131 and 133, and are controlled by needle valves 135. Relatively larger pasageways 136 open into the cylinders 112 and 113, respectively,and into the .passages 128 beyond both valves 131 and 133. passageway 137 opens into each of the passageways 128 between the ball-checks 131 and 133, the passages 137 coinmiinicating, respectively, with pipes 138 and 139 which lead to a valve mechanism 140 shown as formed of la stationary disk-like member 141 containing ports 142, 143 and 144 opening through the upper surface thereof and communicating, respectively, with the pipe 139, an exhaust pipe 145 and the pipe 138, the port 143 being located centrally of the disk and the ports 142 and 144 lying within an are struck from the center of the port 143. The -valve device further comprises a rotatable disk portion 146 shown as set into a circular recess 147 formed in the top of the disk 141 and covered by a cap `member 148 secured to the disk 141 by the bolts 149 and held in the desired relation to the disk 141 by a pivoting member 150 on the cap 148. The under side of the disk 146 contains a ysemi-circular groove 151, so positioned lthat inl the oscillations of the disk ,146, by the mechanism hereinafter described,

compressed air. The `under side of the disk 146 also contains a groove 154 adapted, in the oscillations ofthe disk 146 to alternately a stop 177 ,valve disk 116, com

rnaaaoe conrnect the lports 112 and 1491 with the exhaust port-113, the arrangement being such that when the port 1412 is in communication with the pipe 153the port 1111 is incommunication with the' exhaust, and vice versa.

'llie mechanism shown for operating the l rises .a radially-extending Varm 155 pivotal y connected with a link 166 which in turnispivotally connected, lat 167, with a stem 168 ofa solenoid core 169 reciprocable in asolenoid 170, the Winding o1 which, represented lat171, isfconnected at oppositeends with the contacts 102 and 103 by the wires 172V and 173, there `being any suitable' source of-electrical energy interposed in eitherI of the Wires, such ,as yfor example the battery represented at 1791 in the wire 173. The stem- 168 is surrounded by' a coil spring 17 f3 confined between the adjacent end 'wall 176 of the solenoid 176 and on this rod, this springe' erating to yieldingly force the core 169 an its rod `valve disk 146 to no-rmally occupy the posi# 168to the right in Fig. 13 for causing the tionshown in Fig. 10 and return it to such position when the solenoid 171 becomes deenergized, it being understood from the tore goin that when a passenger steps upon the trea le 98 the circuit through the solenoid 171'is closed-"at.thecontacts 102 and 193 ,thereby drawing .the core 169 into Ithe solenoid` and rotating-the disk 1416 out of the position shown inthe drawings, for a purpose hereinafter described. The solenoid structure referred to is preferably'provided with a dash-pot feature and to this end the part 176 contains "a port 178 openin to the atmosphere andinto the cylinder etween the end 176 and the adjacent'end of the core 169, "with an inwardly-opening ball-check 179, the part`176 also containing a port'180.

.hs the core 169 moves inwardly 'air freely enters the cylinderV through the lports -178 and 180, but in the outward movement ol' thecore 169,'the ball-check 179 closes the passage 178 and slow venting7 of the cylinder of its contained air takes p ce through the port` 180, thereby retarding the outward movement of the'solenoid core 169.

I 'llhe operation ol the gate-controlling mechanism o13 Figs. 8 Vto 13 is as follows the parts ofthe mechanism as illustrated'in Figs. 8, 9 and 10 being shownjin the position they assume alter the door 39`has-been opened tft and the passenger has stepped ed el the treadle 98, yllhe treading upon theplate treadle 98 by a passenger in walking through thoenit-way A36 before alightingfrom the alla i the solenoid car eausesfthe contacts 192 and 193m engage and therebw close the circuit through eistance ol the spring'175 an rotating the disk l1416 in connterlclociae 'direction in i i i l 'L 71 withfthe result ol draw ing. the core 169 inwardly a'ainst the ref ,116 as stated, thereby permits air to pass from the pipe 153, through the valve device to'the pipe 138, thence through the passa el 137 at thaleit hand side of Fig. 9, and t e passages 131 and 136 into the left hand end oli the cylinder portion 112, with the result ot forcing ythe piston device 110,-111 to the right in Fig. 9 to the position therein shown in which operation the shaft 117 is turned in counterclockwise direction in this ii re, thereby moving the crank 118 to the full line position represented in Fig. 8 and the dotted position represented in Fig. '9, the door sections 39 in this operation swinging to open condition as shown in Fig. 8, thereby permitting the passenger'to alight from the car. lin the movement of the piston .11G-+111 to the right in Fig. 9 as stated, the air between the piston 111 and the end wall ofthe cylinder portion 113' exhausts, during the rst portion olf' the movement of the piston, through the passages 129 and 135 at the right hand of Fig. V9 and thence through the pipe 139 and valve to the exhaust pipe 115.-

rllhe continued movement of the piston 111 passing the point at whichY the passage 129 communicates with the cylinder 113 and the continued movement of the piston to a pov'sition o1 rest, is, by reason of the exhausting of the. air through the relatively small 1 outlet at thepassage 135, greatly retarded tor cause the door in its final opening movement .to move` slower than at thel beginning oi the opening movement, the motor 108 as shown, being such asis commonly employed tor opening and closing doors in street car construction and operating the same way'. The coil 171 remains energized. as long as a passenger or a. 'series of passengers walking fairly closely together, maintain. the treadle 98. in depressed condition, but as soon as the passengers discontinue walking on the 1trea/dle 98, it rises, breaking the circuit 169, underv the action ol the spring 175 to move outwardly,thereby movingthe valve throughy the coil 171 and permitting the core y disk 116 in clockwise direction in Figf10 to fr the position shown in this dgure and in Figs. 11, 12 and 13, the movement ot the valve disk 116 tothe position just'stated operating tofcause lluid pressure to dow from the pipe 153, through. the valve device, and4 with the result oit torcin rae 9 from 'the osition therein shown, toward the left han end of the cylinder construction, the shaft 117 being thereby rotated in s clockwise direction in this figure for movingV the door 39 to closed position, the air in the left hand end of the cylinder 112 exhausting therefrom through the valve device of Fig.

10, and producing a retardation ofthe movethe piston device 11G-111 inpits final movement to the left in Fig. 9, as explained of the motor in the operating of the ment o same to a position for opening the door 39.

It will be understood from' the foregoing description that', in' the construction illustrated in Figs. 1 to 7 Q by the engagement of the arm 73 with the notched portion of the lever 75, and in the other construction, by-

the resistance ai'ordedto movement of the doors by the door-operating mechanism, the

barrier means provided cannot be moved to open position Without stepping on the treadle in the exit-way which is not accessi-v ble by persons who might seek to board the carthrough the exit-way, and therefore access to the car cannot-be obtained by any one seeking to enter it through the exit-way.

It is desirable that provision be made for delaying the beginning of the movement of the door 39 to closed position after apassen-` ger has walked beyond the treadle, to avoid closing of the door against the passenger in leaving the exit-way, this being provided for by the dash-pot portion of the solenoid i preventing personsf construction which retards the movement of the valve device of Fig. 10, to the osition therein shown, under the action o the spring 175.v This feature presentsthe `further advantage yof avoiding the flapping of I the doors by the door-operating mechanism,

in thepassage through the exit-way of a -number of passengers closely following each other, the repeated operations of the treadle'- 'under these conditions merely causing the solenoid core and the with to move back an their (parts movable thereforth, but short of the valve of Fig. 10 occupies thepostion therein shown; 1.-

It will bew readily understood .from the foregoing that my invention may bee bodied in other forms than those shown, it

being myl intention not to limit my invefn-l described.
